Bees play a key role in many ecosystems and are important pollinators of flowering plants. Pollination of crops increases yields and improves the quality of the products obtained. Bee keeping also forms the basis of beekeeping, the main purpose of which is to produce different types of honey – nectar, honeydew or nectar-honeydew. The use of probiotics in bees helps to stabilise the beneficial microflora of the digestive system and increases the bees’ resistance to fungal, bacterial and viral diseases.
